Answer 1

Which of the substances P, Q, or R has the lowest specific heat? The temperature v/s time graph is shown P.

Explanation:

Substances having higher specific beats take more time to get heated to a higher temperature and a longer time to get cooled.

If line is drawn parallel to the time axis, it cuts the given graphs at three distinct points. Corresponding points on the time axis shows that

`"t"_"R" > "t"_"Q" > "t"_"p" => "C"_"R" > "C"_"Q" > "C"_"p"`
